Abstract

Now-a-days the requirements of wireless communication are to have high voice quality, high data rates, multimedia features, lightweight communication devices etc. But the wireless communication channel suffers from much impairment. One of them is fading which is due to the effect of multiple propagation paths, and the rapid movement of mobile communication devices. In a typical wireless communication environment, multiple propagation paths often exist from a transmitter to a receiver due to scattering by different objects. Signal copies following different paths can undergo different attenuation, distortions, delays and phase shifts. So, this is necessary to reduce the problem of fading, but not at the cost of additional bandwidth. One effective solution is proposed for wireless system named diversity, without the requirement of extra bandwidth. This paper deals with the Rayleigh flat fading channel and to overcome the effect of fading, diversity is used at the transmitter to get good signal at the receiver diversity combining technique Maximal Ratio Combining (MRC) is used for improving the overall performance of the communication system. The diversity is used to provide the receiver with several replicas of the same signal. Diversity technique is used to improve the performance of the radio channel.
